Ozone → HCID 18926161, compound

Participants

Reaction Steps

1 liter of a solution of 195 g (1.5 moles) of ethylacrolein dimethylacetal in methanol is reacted with ozone at -25° C. to -30° C. analogously to the procedure indicated in Example 1, and is then hydrogenated. The absorption of H2 is 29.55 standard liters (87.8% of theory). After working up, which is carried out analogously to the instructions in Example 2 by removing the catalyst, treating the reaction solution with an acid ion exchanger, distilling off the solvent and rectifying the reaction product, 169 g of ethylglyoxal dimethylacetal boiling at 52° C./15 are obtained, corresponding to a yield of 85.4% of theory.
